ITX cases are where SA small-form-factor builds live or die, and the questions buyers ask are about fit: which GPUs, coolers and PSUs work. The short answer is to confirm clearances before anything else, then choose from proven layouts.

Quick Answer

ITX gaming cases in SA range from around R1,500 to R3,500-plus at Evetech. Critical specs are GPU clearance (commonly up to 320 to 340mm), CPU cooler height (often 55 to 70mm for air, or a 240mm AIO mount), and PSU format, since many compact ITX cases need an SFX unit rather than full-size ATX.

Proven ITX Layouts And Their Limits

Popular ITX layouts split into traditional cube designs and sandwich layouts where the GPU sits beside the motherboard on a riser cable. Sandwich cases like the well-known NR200-style designs support longer GPUs and 280mm radiators but demand careful cable routing. Smaller cube cases limit you to shorter cards and low-profile coolers. Always cross-check your exact GPU length, cooler height and radiator support against the case's published clearances.

SA Buying And Build Notes

An SFX power supply is usually mandatory and costs more than its ATX counterpart, so factor that in. Good airflow is the main challenge; mesh panels and a slim AIO help a hot RTX 4070 Super or RX 7800 XT stay cool. Riser cables in sandwich cases should support PCIe 4.0 to avoid bandwidth loss. Evetech stocks ITX cases, SFX PSUs, low-profile coolers and compatible AIOs, so plan the full clearance picture before committing.

FAQ

What is a sandwich-layout ITX case?

A design where the GPU mounts beside the motherboard on a riser cable rather than below it. These cases fit longer cards and bigger radiators but need careful cable routing and a quality PCIe riser.

Can I use a standard ATX PSU in an ITX case?

Usually not in compact ITX cases, which require an SFX or SFX-L unit. Some larger ITX cases accept ATX power supplies, so check the case spec before buying.

Does an ITX case limit which GPU I can use?

Yes. GPU length is a hard limit, commonly 320 to 340mm in good ITX cases, so confirm your specific card's length, including triple-fan coolers, fits the case.

TIP

sandwich-layout ITX case, make sure the included or purchased riser cable is PCIe 4.0 rated; a slower riser can bottleneck a modern GPU and waste the performance you paid for.
